ISOVER Spacesaver Plus
ISOVER Spacesaver Plus is a glass mineral wool roll with a thermal conductivity of 0.040W/m.K. It is suitable for loft insulation, where it is typically installed in a minimum of two layers, the first layer between the joists and the subsequent layer(s) cross-laid over joists. ISOVER Spacesaver Plus can also be used to insulate ground floor suspended timber applications.
